“…The VAS method is adopted to analyze and predict the overall stiffness of 3D printing composite materials, which mainly includes the following three steps. (20) (1) The effective stiffnesses corresponding to the different micromechanical molded parts of the 3D-printed composite structure are determined. (2) The effective stiffnesses corresponding to different parts of the 3D-printed composite structure in the local coordinate system are converted to the corresponding stiffnesses in the global coordinate system by the coordinate transformation method.…”

Three-dimensional (3D) printing has the main advantages of a high material utilization rate, diversified design, rapid prototyping, the ability to form complex products, high printing speed, and high quality of printed products. Fused deposition modeling (FDM) technology can rapidly generate models with different structural characteristics and then transform the models into actual products. In this study, considering the basic principles of FDM, we first analyzed the process flow and the factors affecting 3D printing. The principle of separating the model and adding support was discussed. Next, the types of support of the model were classified. Finally, the process integrity of different models was studied using examples, and an optimal design scheme for different types of support was proposed. The rapid development of 3D printing technology is expected to realize the effective manufacturing of composite structures with complex geometric shapes, thus further expanding the application range of composite materials. Therefore, in this study, from the perspective of mechanical properties, we analyzed the research status of 3D printing using continuous-fiber-reinforced composites (CFRCs) and performed tests in terms of bending properties. The results show that, on the one hand, adding different types of support can improve the forming process and quality of the products. On the other hand, the effects of bending properties on the mechanical properties and damage evolution law of 3D-printed CFRC products were obtained under typical loads, and a strength/stiffness analysis and a prediction method were used to determine the main factors that affected the mechanical properties.

Piezoelectric actuators have been applied in many research and industrial fields. However, how to improve the working performance of piezoelectric actuators is still a hot issue. Up to now, many new motion principles have been developed for new piezoelectric actuators. The bionic type piezoelectric actuator is a kind of the novel piezoelectric actuators, and it imitates the motion style of different creatures in nature to overcome the limitation of traditional piezoelectric actuators. Bionic type piezoelectric actuators are able to achieve large working stroke or large output force, which is of great significance for the development of piezoelectric actuators. The principle, design, and future of some bionic type piezoelectric actuators are discussed in this chapter.

“…The adhesive layer effect was usually neglected in the design stage. The FV method was also used for the modeling of piezoelectric motors, and the dynamic characteristic of stator and the contact principle between stator and mover were investigated (Bolborici et al, 2014; Renteria Marquez and Bol-borici, 2017; Renteria-Marquez et al, 2018). The 3D FE model of a bonded-type piezoelectric rotating motor considering the adhesive layer was simulated by Wang et al (2006).…”

This paper provides a general framework for modeling bonded-type piezoelectric linear motors considering the stress transferred by adhesive layer. A three-dimensional static model of stator is first developed by the principle of minimum potential energy and finite element. The stress transferred by adhesive layer could be simulated and analyzed for arbitrary bonding conditions. Basing on the static stress-transfer analysis, a quasi-static stress acted to substrate by piezoelectric elements is assumed and integrated into the substrate dynamic model. A pure mechanical dynamic model is developed for the electromechanical coupling system of stator. Furthermore, the whole-machine dynamic model of motor is presented by incorporating the frictional contact force into the dynamic model of the stator and an analytical model of the mover. Finally, a bonded-type piezoelectric linear motor with V-shaped stator is investigated as an example for simulations and experiments. The methodology presented here for simulating the transferred load of adhesive layer in bonded-type piezoelectric motor as well as for estimating the vibration characteristics of stator and output performances of motor. It is believed that the proposed method would be helpful to design and manufacture the prototypes due to the wider applicability of allowing for irregular geometry and any bonding conditions.
